until its pin 66 engages the locking device 68 vand is againlocked in position. The car is then ready to receive a new load.

' ltwill be apparent from the foregoing description, that the car bed, when in carrying psition., is at all times locked against tilting ateither side7 and that after it has been dumped at either side the lockingdevices at the dumping side remain operative, 'so that when the bed is restored to its horizontal. position it cannot tip over to the other' side without the actuation of the appropriate piston'.

' insonne cases it is desirable to remove the side gates of the car in order to enable itto receive a'large amount of stone or other load which extends beyond the side gates, or for other purposes, and as in such case the side gate operating bars 18. are also removed, it is necessary that other means provided for connecting thesvvingingmembers 60-61 with-.the car bed in order that the locking mechanism may act thereupon. In such circumstances l connect the sides of the car bed with the swinging' members (iO- 61' by suitable connections, such as chains S0, shown in' Fig. 7, the operation in this case being the same as that already described, except that the car bed is held against tilting when loclmd by means of the chains instead of by the side gates and their connections, t

That which l claim my invention, and desire to secure by Letters ltatent.y is,

l. A du rap-car, comprising a suitable support, a rocking car bed7 a swinging member mounted on said support and operatively connected with one side of the car bed so as to swing` when said bed is tilted to dump its load at the opposite side of the car, loclring means for normally holding said swinging member against movement, a rock-shaft connected with said locking means and adapted when rocked to release said swinging member, a liuidepressureoperated piston, and connecting means normally connecting said pistonand roch-shaft so that said rock-shaft is rocked by the action ot the piston, said connecting means being adapted to be actuated by the tilting of the bed in one direction to disconnect the piston 'from the rock-shaft.

2. A dump-car, Comprising a suitable support, ay rocking car bed, amazing-ing' member mounted on said. support and operatively connected with one side of the car bed so as to swing when said bed is tilted to dump its meines load at the oplosite side of the car, locking.

means for normally holding s'aid swinging" tons and actuated thereby to engage the bed for tiltingthesame, locking mechanism for normally locking the bed in operative position, and means actuated by said arms for releasing said locking devices to permit the bed. to be tilted, the arm ou the discharge i.
